A baker is decorating the top of around cake with cherries. The diameter of the cake is 9.5 inches. Each cherry is 0.75 inches in diameter. About how many cherries will the baker need to decorate the perimeter of the top of the cake?
idk - i don't know how to answer this problem can you help me pls i am trying my best to not fell me test.
C = pi * d
C = 3.14 * 9.5
C = 29.83 inches
29.83 / 0.75 = _______ cherries
To find the number of cherries needed to decorate the perimeter of the top of the cake, we need to determine the circumference of the cake and divide it by the diameter of a cherry.
1. First, let's calculate the circumference of the cake. The formula for the circumference of a circle is C = πd, where C is the circumference, and d is the diameter. Given that the diameter of the cake is 9.5 inches, we can calculate the circumference as C = π * 9.5.
2. Next, we need to find the number of cherries that fit along the circumference. To do that, we divide the circumference by the diameter of a cherry. The formula for fitting circles around a circumference is N = C / d, where N is the number of circles, C is the circumference, and d is the diameter of a circle. In this case, N = C / 0.75.
Let's compute the calculations:
C = π * 9.5
C ≈ 3.1415 * 9.5
C ≈ 29.845 inches
N = 29.845 / 0.75
N ≈ 39.793
Therefore, the baker will need approximately 40 cherries to decorate the perimeter of the top of the cake.
